Grape grafting double root cultivation method
Grafting with Fujiminori and Kyoho grapes, and retaining the growth of scion and double roots of Fujimaki, it has obvious growth advantages, such as accelerated growth, leafy foliage, early results, enhanced disease resistance, increased fruit setting rate, and high yield stability. 1. Method of operation The Fujieda and Kyoho grape seedlings (or the cutting seedlings of the previous year) were planted close to each other and they were planted after the budding in spring or during the growing season. The method is: the two seedlings within 10 centimeters from the soil within the smooth and unwieldy easy to operate parts, each cut 3 cm long noodles to expose the formation of layers or cut to the pith, and then tie the two corresponding cut surface together (Available The plastic band tied), after 1 month, after the scion survived, the Kyoho grape was cut off from the upper end of the healing part, leaving the rattan seedlings to continue growing and pruning. From the second year onwards, it slowly entered the result period. 2. Advantages The root system of the Kyoho grape is extremely developed, and even in the high groundwater season or in the rainy season, it still has a strong ability to grow and adapt to the soil. The original root system of Fujiminori grape still maintains its normal growth capacity, which greatly enhances the water, fertilizer and nutrition needed for the growth of newly-grafted seedlings. Through the grafting of Fujieda vines, the advantages are strengthened, the growth and development are accelerated, and the ear and fruit are increased. At maturity, they are 7-10 days earlier than Kyoho grapes, and the disease resistance is also strengthened, which is 15% higher than that of the control Fujiminori grapes. -20%. 3. Management 1 Strengthen fertilizer and water management. Because the newly-grafted seedlings are particularly well-developed root systems, and their ability to absorb water and fertilizers is increased, it is necessary to increase fertilization and water supply in order to achieve high yields as soon as possible. 2 timely pruning, the results of the sparse fruit thinning to prevent lust green late. 3 pay attention to pest control. Do a good job in the control of pests such as black pox, anthracnose, downy mildew, powdery mildew, and winged moth.
